Tongue print is as unique as a fingerprint no two people have the same pattern of bumps, ridges and papillae on their tongue. Scientists say this uniqueness comes from the arrangement of taste buds and surface textures, making it a potential biological identifier. Beyond identity, the tongue also helps us detect harmful or toxic food through taste and plays a role in gripping and moving food while eating. Unlike fingerprints, the tongue is protected inside the mouth making its pattern more resistant to wear and damage.
